证明了具有约束控制半线性热方程系统的不能控性;满足一定条件的目标的可达性;最后证明了当控制区域U是有界闭集时,系统的等时区域与控制区域是U的凸包时的等时区域相同,推广了有限维的结论。
2.
It is proved in this paper that, the reachable set of system, in which the state varible is linear and control varible is nonlinear, must be boundedly convex-closed set provided that the control domain is boundedly closed set.
严格证明了,当控制区域为有界闭集时,状态变量为线性而控制变量为非线性的系统的等时区域是有界凸闭集,从而用等时区域方法能彻底解决这类系统的时间最优控制问题。

补充资料:区域经济规划(区域规划)
区域经济规划(简称区域规划)是区域经济发展战略的具体安排,是战略思想的细化。区域规划应当是区域经济发展战略指导下的区域和产业发展的详细的安排。它包括区域发展、产业发展、土地利用、城镇体系等多方面的内容。它与发展战略的主要区别在于,战略应是粗线条的、具有指导意义的纲领;规划应是细线条的,具有实施功能的安排。
